Seventeen year old Anthony Terrell Jr. was arrested and charged Friday with k!lling his mother and two younger sisters.

Gwinnett County Sheriff’s Deputy Joy Deleston, 39, and her two daughters, Micaiah, 11, and Jelani, 4, were found late Thursday at their home near Lawrenceville, Ga.

The motive for the k!llings is still under investigation and according to various news sources, the youngest victim Jelani was the daughter of rapper Juvenile.

Terrell is being held without bail in the neighboring DeKalb County jail to avoid any potential conflict because his mother worked for Gwinnett County.

Jeff Beaird, who lived across the street from the family, said he often saw Terrell playing basketball or washing his mother’s patrol car in the driveway but doesn’t remember anything out of the ordinary. “It’s so shocking because you don’t expect something like this to happen,” he said.
